Can anyone tell me what this is???????????

This chick is just huge compared to the other ones..... everything about it is huge! Is it a meat chicken ???? There is supposed to be a Buff Orpington rooster and 5 hens but this chick is just huge! The other breeds I ordered are RIR, EE's, B. Rocks, Hubbard Isa Browns, Grey Leghorns, and Black Australorps. Unless it is one of the orpingtons , than I don't know... they came from Townline.
